An unorthodox Indian music star has won hearts online with her big teeth, lustrous white coat, four legs and melodic braying at mealtime.

Emily, a donkey living at an animal shelter in the Indian city of Pune, became an internet sensation last year after a clip of her "singing" went viral.

Staff at the center were playing with Emily when she started crooning.

They recorded a video of Emily showing off her vocal range and uploaded it onto their social media page, where it became an instant hit.

"Usually our videos have a lot of sick animals and animals being rescued, and it's generally heavy and sad," RESQ Charitable Trust head Jessica Roberts told AFP.

"So for a change we decided to put this video of Emily singing, and the response from the public has been amazing," Roberts said they were inspired by Harriet, a singing donkey from Ireland who also shot to social media fame for her "operatic singing."
